Recirculating three-pass fire-tube steam boiler. Equipped with an offset furnace tube wet-back structure, high-temperature flue gas sequentially washes the second and third pass flue tubes, and then is discharged into the atmosphere through the rear smoke chamber and chimney. The boiler features movable front and rear smoke chamber covers for easy inspection. It is equipped with a technically advanced burner with good combustion, featuring automatic proportional adjustment of combustion, automatic water regulation, programmed start and stop, and full automatic operation. It also has automatic protection functions such as high and low water level alarms, extremely low water level, overpressure, and shutdown. This type of boiler boasts compact structure, reliable safety, easy operation, rapid installation, low pollution, low noise, and high efficiency.
Key Features:
1. Our gas steam boiler features a reasonable, compact, and island-type overall structure, meeting the requirements for quick assembly upon delivery. The product is composed of three main sections upon leaving the factory: the boiler main unit, chimney, and pipeline system. Both the main unit and chimney sections are fully manufactured in our factory. The pipeline valves and instruments for the main unit are pre-installed. Upon arrival at the site, simply assemble the main unit and chimney. Connecting the gas, power, and water supply lines allows for immediate testing. This significantly reduces the installation period while ensuring product quality.
The boiler design enhances its performance. The main boiler body is an integrated structure, with the burner assembly on the front smoke box cover, and the main body mainly arranged for the heating surface and combustion chamber sections. It boasts a reasonable and compact structure, low steel consumption, a bias-structured corrugated furnace tube, and insulation with a new lightweight thermal insulation material. The outer packaging is made of colored thin plates, with a rectangular shape, making the boiler's performance, weight, structural dimensions, and appearance significantly superior and aesthetically pleasing compared to domestic products of the same capacity. The water supply equipment of this boiler is configured on the boiler base on the right side, integrating it with the main body and eliminating the need for an additional foundation.

Steam Separator - The steam separator is a primary auxiliary equipment for boilers, used to distribute the steam generated during boiler operation to various pipeline routes. The steam separator is a pressure-containing device, classified as a pressure vessel, and its pressure-bearing capacity and volume should correspond to the matched boiler. The main pressure-bearing components of the steam separator are: the head and shell materials are all Q235-A/B, 20g, 16MnR, with specifications ranging from φ159 to φ1000. The working pressure is 1-2.5 MPa. Special specifications can be arranged for design upon customer request.
